5 claims. (c1. 'i4-#547i This invention relates to rotary control handles and particularly is directed to improved mechanism for raising and lowering the windows of automobiles or other vehicles, the object, generally stated, being to provide an improved handle which, when not in use, may be recessed within the door to eliminate interference with the vehicle occupants, which provides a symmetrical design of the fitting to render the same more attractive, and which generally is more advantageous than the rigid crank-arm arrangements conventionally employed.

The invention consists in the novel construction, adaptation, and combination of parts hereinafter described and claimed, the preferred embodiment being illustrated in the accompanying drawing, whereinz-f- Figure 1 is an elevational view representing the invention as applied to anV automobile door.

Fig. 2 is an enlargedplan view of the invention; and

Fig. 3 is a transverse vertical section taken on the line 3 3 of Fig. 2.

Particularly as respects the drawing, the reference numeral 5 represents an automobile door provided with a window 6 supported for vertical movement by means of well-known or suitable lever or gear mechanism which, as indicated, includes a shaft I supported for rotary movement and protruding from the inner side of the door.

According to the present invention, the xedangle crank-arm conventionally utilized to impart rotary movement to said shaft is replaced by a member Il] of a relative disk shape formed with a centralf socket arranged to iit over a squared extension 8 of the shaft 1, a screw II securing the same. Provided by said disk member is a radial cavity I2 the function of which is to house a handle I3 to normally locate the latter in a recessed position flush or nearly so as respects the surface of the disk member, said handle being pivotally mounted by means of a pin I4 carried by the disk member at the outer limits of the cavity. The handle, as represented by full and dotted lines in Fig. 3, is adapted for movement from normal recessed to an'exposed position lying at right angles to the plane of movement of the disk member, and for yieldably maintaining the handle in either of said selected positions, the hub I5 of the handle desirably is `formed with planed surfaces I5 disposed to enmatically return the handle to recessed position following use of the same. The cavity I2, as indicated, is somewhat of a pear-shape to form nger recesses laterally of the handle in facilitating the withdrawal of the handle to its crankforming position.

To aiord an open chamber within which the disk member is rotatably received, I provide a plate element I'I which preferably is designed to fit an annular recess I8 formed in the inner wall of the vehicle door, the plate element about its perimeter having a trim-forming flange I9 which operates to vcover the edges of velour or other upholstery 9 employed in surfacing the door.

The invention should be clear in its provision of a window-control arrangement which, when not in use, lies ilush with the surface of the door in a manner to prevent the same from interfering with the driver or other occupant of the vehicle either when entering and leaving the vehicle or while riding in the same.

Modifications of the invention will readiy appear and it is my intention that the invention shall be limited only as by expressed restrictions in the hereto annexed claims.

What I claim, is:-

1. In combination, a rotary spindle, a wall structure through which said spindle extends formed with an exposed cylindrical chamber lying in concentric relation tothe spindle, a disk, operatively engaging the spindle for rotating the latter, revolubly received in the wall chamber and formed in its exposed surface with a recessed cavity which lies in radial relation to the disk to locate the same between the center and the perimeter of the disk, and a crank handle for operating the disk pivotally received in the disk vrecess with its pivotal axis outermost for movesame disposed radially of the disk to locate the gage a .fixed spring I6 secured to the oor ofA the cavity. Any suitable spring, replacing the fixed spring I 6, might as readily be used in modifying the construction where it is desired to autocavity between the center and the perimeter of the disk, a handle-supporting shank pivotally received in said cavity for movement from a normal recessed position relatively ush with the disk surface to an upstanding position relatively at right angles to the plane of movement of the disk, and a handle-forming member sleeved over the shank for relative rotary movement, the pivoted hub of said shank lying in the restricted throat of the cavity and toward the perimeter of the disk whereby the sleeve lies in the greater expanded portion of the cavity and toward the disk center, said expanded portion of the cavity being of a width to permit the introduction of the fingers of the operator at each side of the sleeved handle for withdrawing the handle from the cavity.

4. In combination with a rotary spindle having its end projecting from a wall structure into. a recess formed therein, crank mechanism for the spindle comprising a disk member revolubly Vreceived in the wall recess to lie in flush relation to the surface of the wall, and a cranking arm pivotally carried by the disk member for movement from a normal recessed position at which the same lies flush with the disk member and with the surface of the Wall to an exposed operating position at which the arm extends in parallel Arelation to the axis of the disk member from the perimeter of the latter, the length of said arm being less than the radius of the disk.

5. Crank mechanism for a rotary spindle comprising a single-thickness sheet metal disk stamped to provide a central socket by which the same is fitted over the spindle and a recessed cavity lying between the spindle-tting hub and the perimeter of the disk, and a cranking arm normally disposed to lie in recessed relation to the disk within the cavity and pivotally coupled to the disk for movement from its recessed position into an exposed operating position at which the arm extends in parallel relation to the axis of the disk from the perimeter of the latter.
